Drone waiters unveiled at a restaurant in Singapore

Food is a national obsession in Singapore, but the country doesn't have enough people working in restaurants to get the food from the kitchen to the customer.

One company thinks it has found the answer - a group of flying drones which can automatically deliver your dinner.

Infinium's robots whizz above the heads of diners on paths mapped out by a computer program, and find their way using infra-red sensors placed around the restaurant.
